This annual project includes televising, repairs and rehabilitation of existing sanitary sewer. The program also detects and eliminates points of

Report. The projects were reviewed by Metropolitan Council and approved in lieu of surcharge fees.

..f9stijication I
'~~ltYst#flj~~identified numerous older sewer lines that are in need of repair. The City of Chanhassen pays the Metropolitan Council for sewage
.z' tteatIn~nt. Those payments are based on the amount of flow generated by the City of Chanhassen. Surface water and ground water that makes its
Wi way into the system either through breaks, displaced joints, manhole covers, or private connections to the system increase the amount charged to
.~ the City for sewage disposal and increasing the load on the City's lift stations. Also, MCES may place a surcharge on cities that are not trying to
~improve the inflow and infiltration problem.

:tlie efforts may decrease operational costs, emergency call outs and maintenance costs. It is also the city's intent to use connection charges to help
; fund for those costs. It is the city's belief that as new customers come on line those connection fees should help fund future infiltration problems.
